fMRI, machine learning could predict OCD therapy outcomes
By Wayne Forrest
By analyzing resting-state functional MRI (fMRI) brain scans with a machine-learning algorithm, researchers at the University of California, Los Angeles may have devised a way to predict treatment outcomes for people with obsessive-compulsive disorder (OCD), according to results published online February 12 in the Proceedings of the National Academy of Sciences.

Can AI help in the fight against gadolinium deposition?
By Erik L. Ridley
What if gadolinium-based contrast agents could be used at just 10% of current dose levels without significantly degrading image quality or contrast enhancement? Artificial intelligence (AI) could make that possible, according to research published online February 13 in the Journal of Magnetic Resonance Imaging.

DTI-MRI ties lack of fitness to cognitive decline
By Wayne Forrest
With the aid of diffusion-tensor MR imaging (DTI-MRI), researchers from the University of Texas Southwestern Medical Center have discovered that a lack of physical fitness can lead to deteriorated nerve fibers in the brain and eventually cognitive decline, according to a study published in the February issue of the Journal of Alzheimer's Disease.

Havana embassy case baffles clinicians -- despite MRI
By Brian Casey
What caused a series of mysterious illnesses among diplomatic personnel at the U.S. embassy in Havana in 2016 and 2017? A study published February 15 in the Journal of the American Medical Association hints at symptoms similar to concussion but without evidence of trauma. And MRI scans were unable to shed light on the mystery.

Study finds gadolinium leaks into eyes of stroke patients
By Wayne Forrest
Researchers from the U.S. National Institutes of Health found that gadolinium from MRI contrast can leak into the eyes of stroke patients who receive scans. They don't understand the mechanism of the leakage, although it may have some clinical consequences, according to a February 7 paper in Neurology.
